To a/ZZ whomJ it may concern.'

Beit known that I, FRED L. BEYMER, a citizen of the United States ofAmerica, residing at Indianola, in the county of Warren and State ofIowa, have invented certain new and useful Improvementsin Sheet-MetalHeating- Stoves, of which the following is a specication.

Myinvention relates to that class of sheetmetal stoves in which thefire-box is inclosed in a sheet-metal casing; and my objects are, first,to provide a radiatingflrum of simple, cheap, strong, and durableconstruction designed to receive the products of combustion arising fromthe stove and utilize it to its maximum capacity in heating, and eithera direct or indirect draft be provided.

A further object is to provide a stove-front having flanges to receivesaid stove body and casing, wi th draf t-passages cast integral therewith and extending between the said iianges, so as to be exposed to thegreatest possible degree of heat and yet not be liable to burn out bydirect exposure to the fire.

'My invention consists in certain details of construction, arrangement,and combination of parts whereby the results contemplated are attained,as hereinafter set forth, pointed out in my claims, and illustrated inthe accompanying drawings, in which- Figure 1 shows the complete stovein side elevation. Fig. 2 shows a vertical section on the line 2 2 ofFig. l, also showing one of the air-feeding pipes in section. Fig. 3shows a vertical section on line 3 3 of Fig. l. Fig. 4 shows a verticallongitudinal section on line 4 4 of Fig. 2. Fig. 5 shows a horizontalsection through the radiating-drum and an arrow indicating the usualline of draft therethrough. Fig. 6 shows a like view, in which thedirect draft is indicated by dotted lines and the most circuitous draftby an arrow. Fig. 7 shows a detail sectionalview of the rear end of thestove to show the connection of the stove body and drum with the rearupright. Fig. 8 is a like view showing a modified form. Fig. 9 shows atransverse section of a modified form of drum, and Fig. 10 shows a likeview of another modification.

Referring to the accompanying drawings,

the reference-letter A is used to indicate a cylindrical sheet-metalfire-box supported in the cast-metal ends B and B2, which have theintegral feet B3.

C-indicates an oval sheet-metal stove-body which I have provided withaperforated bottom at C2 and a screen C3 at its top to permit a freecirculation of air therethrough.

I have provided means for admitting heated air to the fire-box to aid inproducing complete coinbustion by casting upon or attaching to the rearsurface of the frontB two airpassages C4, having their upper ends openat the front and their lower ends leading into the iire-box at oppositesides, the passages being brought into close proximity to thecombustion-chamber, so as to heat the air as it passes therethrough.

D indicates a srnoke-pipe communicating with the rear top portion of thefire-box and leading to a radiating-drum.

The means I have provided for increasing the radiatingsurface andproviding for a direct or a tortuous passage for the smoke coinprises aradiating-drum F, semicircular in transverse section, open at its ends,and having two longitudinal vertical partitions Fzand F3, extended topoints near the ends of the drum, the partition F3 being shorter at itsrear end than the other oneJ for purposes hereinafter made clear. Apartition F4 eX- tends from the rear end of the partition F2 to the sideof the drum farthest from the partition F2, and dampers are provided atH and H2, so that the draft may be directed in either of the three waysindicated in Figs. 5 and 6. The arrangement of the dampers necessary toaccomplish this will be readily understood by reference to said figures.

The flue-pipe J leads upwardly from the central portion of the flue onthe left-hand side of the drum.

K indicates a cleanout and check-draft Ydoor in the front B tocommunicate with the drum.

In Figs. 7 and 8 two means for connecting the stove bodyand drum withthe end pieces are shown. In each instance, however, the

flanges K2 are beveled on their upper or under surfaces, and by forcingthe body or drum IOO IOy

up to the end the edges of said body or drum are expanded and a tightconnection thereby provided.

In Fig. 9 a radiating-drum, oval in transverse section, is provided inlieu of the semicircular or the preferred form, and in Fig. 10 arectangular drum is illustrated. In each instance, however, theoperation is the same, and the same beneiicial results are attained.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent of the United States therefor, is-

l. In a sheet-metal stove having a suitable iire-boX, and upright endpieces for supporting the same, the combination of an openended drum7designed to be supported in the said end pieces above the stove-body,and

having an opening at its bottom near one end to admit a pipe from theLire-box and a discharge-opening at its top, two longitudinal partitionstherein extending' to points near the ends of the drum, a transversepartition extending from the end of one of said partitions to theopposite side of the drum and having a draft-passage therein to provideopen draft-passages from the opening that leads to the fire-box directto the dischargeopening and from the Hue-opening through the middlepassage and partly through the remaining outer passage to thedischargeopening and dampers to control the direct passage and tocontrol the passage leading around the interior to the flue-opening,substantially as set forth.

2. A sheet-metal stove comprising two oval cast-metal end pieces, anoval sheet-metal body fixed to said end pieces, a cylindricalsheet-metal fire-box located in the lower portion of said oval metalbody and iiXed to said end pieces, a radiator having a tortuous passagefor the products of combustion inclosed within the oval metal body andabove the iirebox and means for conducting and controlling the passageof the products of combustion from the {ire-box through the radiator inthe manner set forth, for the purposes stated.

3. The combination in a sheet-metal stove, of a cast-metal front havingan inwardly-projecting flange, a sheet-metal stove-body with its endoverlapping the iange, two fines cast integral with the stove-front andleading from a point near the top of the stove, downwardly on the rearsurface of the stove-body in close proximity thereto but not in directcontact with the iire at any point, and discharging into the stove-bodyat its bottom, to produce a downdraft-iiue that will superheat air andyet not burn out, substantially as set forth.
